First Minister Alex Salmond has insisted he will take just one parliamentary salary.
Alex Salmond has been paid as both an MSP and MP
Earlier it had emerged he has been paid by both Westminster and the Scottish Parliament since he became an MSP in May's Holyrood elections.
Mr Salmond said he would continue claiming his MP's salary and repay the money he has received from Holyrood.
Before the Scottish election said he would draw just one salary if he was also elected as an MSP.
Under the terms of the Scotland Act, politicians sitting in both Holyrood and Westminster, are entitled to an MP's salary of £60,000 plus a third of the £53,000 paid to MSPs.
In addition, Mr Salmond, who is the MSP for Gordon and MP for Banff and Buchan, collects a further salary of £77,000 as first minister.
He said arrangements were being put in place for him to receive only one of the parliamentary salaries.
Mr Salmond said he believed he would be the first person who had been elected as both an MP and an MSP to take only one wage.
He said: "My intention is I will be taking one Parliamentary salary.
"Arrangements are being made and an announcement will be made shortly."
He added: "I think I will be the first person in this position only to take one parliamentary salary.
"It can be done and I will do it. But it's not quite as simple as you might think it should be."
A spokesman for Mr Salmond said later: "These arrangements will be backdated to the election."
But Liberal Democrat Scottish spokesman Alistair Carmichael said the first minister had promised not to take his pay from Westminster.
He said: "Alex Salmond won the votes of the people of Scotland on the express promise that he would not continue to draw his Westminster salary.
"He now needs to explain why he has continued to take that money. If he does not now repay it his standing as a politician will suffer enormous damage."
Scottish Tory finance spokesman Derek Brownlee said: "Alex Salmond has said he is going to sort it and for the sake of his and his government's reputation he had better sort it soon."
